Vacuum Brake Booster: Description and Operation

Brake Booster

The vacuum type power brake booster:
- is a dual diaphragm, vacuum assisted power brake booster.
- reduces brake pedal force and travel distance.
- is located on the LH side of the cowl in the engine compartment, between the brake pedal and the brake master cylinder.
- is divided into separate chambers by the diaphragms.
- will not operate if vacuum fails.
- is installed as an assembly.

If the power assist fails, the brake system continues to operate with increased brake pedal effort.
